VR-based Research And Design On GPS Simulation And Training System

With the development of modern educational technology,especially the development of multimedia computer simulation technology and virtual technology, people have gained a deeper understanding of the use of computer simulation technology in the field of vocational education.For some teaching content which is dangerous and hardly to be expressed,the three-dimensional simulation of a teaching environment is created with the use of information technology.It significantly improved the effectiveness of teaching.Therefore,the research and realization of the simulation of three-dimensional teaching in computer is of great social and economic significance.In this essay,from the perspective of three-dimensional simulation of teaching, research is executed to achieve the computer simulation and training of GPS measurement system in a computer.First of all,the application of GPS system is introduced in the various fields and the background and significance of the subject are explained in detail.In this essay,the principles of GPS measurements and the TopSurv are studied in the actual measurement.The application of simulation methods of GPS system and WGS-84 coordinate model are proposed and the composition and design of the system is concretely pointed.In the software part,considering the various objectoriented programming language features,The TopSurv programming can be realized using Delphi language and finally the VR virtual technology is applied to achieve the training of GPS system.In this essay,the actual appearance and function of GPS system is completly displayed.In the process of application,users can be satisfied and the system can be operated in accordance with the real instruments for the simulation measurement in construction process.System design meets the users' basic training and equipment requirements in the aspect of the teaching experiments and GPS system gain a greater promotion in the value of theory and practical application.Combination of the theory and practical application for the GPS system,a meaningful exploration is achieved through research and implementation.
